For too long a wretched code
Enslaved men to men:
May the reign of the brigands fall!
Let us finally know what our condition is
Awaken to our voice
And leave the darkest night behind,
People! Take hold of your rights,
The sun shines for all.

You created us to be equal,
Nature, oh beneficent mother!
Why, in property and labors,
This murderous inequality? Awaken!

…

People, smash the ancient charm
Of a too lethargic slumber:
With the most terrible of awakenings
Spread alarm to grinning crime.
Lend an ear to our voice
And leave the darkest night behind.
People, take hold of your rights,
The sun shines for all.

In the uncertain aftermath of Robespierre’s fall, the interregnum of the Directory saw both royalists and republicans jockey for a restoration of their former prerogatives (and jockey against one another, of course). Babeuf’s conspiracy might have been the boldest stroke of all had it come off; instead, a projected rising for May 11, 1796 was scotched by Babeuf’s pre-emptive arrest.

But to strike the head was not to slay the movement. The economy was a mess and the political authority a rudderless, unpopular clique. The coup attempt didn’t happen but Jacobin agitation continued to mount — met in its turn by royalist agitation, the two parties dangerously hellbent for one another’s blood. The imprisoned Babeuf (he wouldn’t be guillotined until the following year) made one such focus of agitation — and eventually, of more conspiring.

Babeuf’s allies conceived a plan of swaying the regiment of dragoons then encamped on the plain of Grenelle outside of Paris. (Today, part of the 15th arrondissement.)

On the night of September 9-10, several hundred armed Jacobins assembled and descended on the camp of Grenelle — intending not to fight, but to fraternize, hoping that sympathetic soldiery could be swung to liberate Babeuf and mount a rising against the Directory. This strange and desperate episode was in the end the acme of babouvisme, and was crushed out of hand by officers of the regiment.

Most of the would-be fraternizers scattered but 132 were arrested. At snap military trials — legally questionable since most of the instigators were civilians — 33 death sentences were meted out. Three were delivered in absentia; the 30 others were all enforced by musketry on this date.

The most notable casualties among those 30 were (these are French Wikipedia links all):
